Specification of Letters Patent.

Original application filed June 28, 1909, Serial No. 504,878. Patent No. 1,138,437. Divided and this application filed May 3, 1915. Serial No. 25,568.

To all whom it may concern:

Be it known that 1, CHARLES L. BAENDER, a citizen of the United States, residing at Oakland, in the county of Alameda, State of California, have invented certain new and useful Improvements in Carpet-Sweeping Appliances, of which the following is a description, reference being had to the accompanying drawing and to the figures of reference marked thereon.

The present application is a division of my application filed June 28th, 1909, Serial No. 504,87 8, patented May 4, 1915, No.

The subject matter of this division relates to a carpet sweeping appliance in which means are provided for adjusting the weight of the forward or nozzle end of the sweeper, said means including a corrugated or roughened shoe which will stir up the; pile of the carpet and loosen the dust to enable it to be more readily sucked into the dust receptacle through the nozzle by the action of the suction bellows. y

The invention is illustrated in the accompanying drawings, in which I Figure 1 is a plan or top view of my improved carpet sweeper,

Fig. 2 is a sectional elevation of the carpet sweeper,

Fig. 3'. is a perspective view of'the nozzle with corrugated plate formed thereon, and

Fig. 4 is a detail view of the corrugated shoe for raising or lowering the nozzle.

It is not herein deemed necessary to refer to and describe particularly the parts of the apparatus which form the subject matter of the 'parent case as reference may be had to such application for these features.

The dust receptacle. is shown at 1 and the pair of suction bellows 2 and 3 are arranged on the top of the body or casing 4 to which the receptacle is detachably connected; the bellows may be constructed in the usual way of the movable top board 5 and .a flexible, collapsible diaphragm '6 air be-' ing drawn from the dust receptacle through ports 7 in the bottom 8 and expelled through outlets 9 in the movable top boards.

' These top boards are alternately operated and connected by suitable cam and, lever connections as shown in Fig. 2 with the traction wheels W. The dust receptacle is divided by a partition 10 into a compartment 10 for the lar er particles and a pocket 10 in which the er particles of dust are collected and retained. These compartments are separated from the bellows by a screen 11 placed under the ports above referred to, the interstices or apertures in which screen Patented Jan. 6, 1920;

are sufficiently fine to prevent the fine dust from being carried out by the air currents.

The means for raising the pile of the fabric being swept and dislodging the dust therein as also for adjusting the pressure of the nozzle of the carpet sweeper on the carpet is shown more in detail in Fig. 1. This comprises a corrugated shoe 12, one end of which is suspended by a crank rod 13 from hangers 14 on the sides of the casingi- One endof the crank rod terminates in a handle 15 on the outside of the hanger 14 and by means of stop pins 16 'on the side of the casing, the handle may be lockedor fixed in any one of several angular positions the efieet of which is to raise or lower the shoe at the front end. By this adjustment the contact of the bottom of the nozzle with the carpet is regulated with the effect of causing the nozzle to bear with'varying degrees of pressure on the carpet under the weight ofthe cleaner. r I As thus arranged it will be obvious that the weight of the load at the front end can be thrown either entirely on the nozzle or partly on the nozzle and partly on the shoe. This adjustment is made from the forward end, the opposite end being attached to the bottom of the receptacle by hangers 17.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is 1. A pneumatic cleaner having traction wheels supporting the rear thereof, a dust receptacle, a suction nozzle adapted to support the front end of the receptacle and communicating with the interior thereof, means for creating a suction through the nozzle and dust box, and means for varying the pressure of the nozzle on the surfacebeing swept, said means comprising a shoe adjustably secured to the bottom of the receptacle, said shoebeing composed of a corrugated plate.

2. A neumatic cleaner. havmg traction wheels supporting the rear thereof, a dust receptacle, a suction nozzle adapted to supcorrugated plate including a crank rod de-' -port the front end of the receptacle and pending from the. casing and engaging said communicating with the interior thereof, plate. means for creating a suction through the In testimony whereof I affix my signature, '5 nozzle and dust box, and means fgr varying in the presence of two Witnesses.
